How to choose a identity resolution tool

Identity resolution is most valuable for two use cases: de-anonymizing website visitors (IP-to-company matching) and unifying fragmented customer records across systems. B2B identity resolution tools (FullContact, KickFire) focus on the former. CRM enrichment tools like Enrich-CRM focus on contact and company data accuracy within your existing CRM. If you need both, they can be layered: identity resolution identifies the account, CRM enrichment keeps the contact data current.

Frequently asked questions

What is the best identity resolution tool for B2B?

FullContact and KickFire are leading B2B identity resolution tools for website visitor de-anonymization. For contact-level identity resolution within your CRM (matching fragmented records, enriching incomplete contacts), Enrich-CRM uses a live-lookup approach that covers 150+ countries with ~94% match rate on company domains.

How does identity resolution differ from CRM enrichment?

Identity resolution identifies who an anonymous visitor or fragmented record is — matching IPs to companies or merging duplicate records. CRM enrichment adds attributes to known records: job title, company size, tech stack, LinkedIn URL. Both are complementary: identity resolution discovers the entity, CRM enrichment fills in the details.
